Samsung Fridge / Smartthing Rest API

[DarthPaul]

With some help fom Admin, I have finally succsessfully Set up a API to fetch Data from Smartthings Cloud.

I have a Samsung fridge, with a Smartthings VLAN Dongle innstalled.
You need an Smatphone, Smartthings-APP and account, and set ut the Fridge to communicate to the Cloud.

Thereafter you can with your account credentials access the Cloud and set up a PersonalAccessToken
link to get new token:
https://account.smartthings.com/tokens

--Script under was placed in Resident, sleep 20sek

Code:

https = require('ssl.https')
json = require('json')
ltn12 = require('ltn12')

token = 'Secret-number-from-weblink-above'

tbl = {}
res, code = https.request({
  url = 'https://api.smartthings.com/v1/devices/--Device-number--/status',
  method = 'GET',
  headers = {
    ['authorization'] = 'Bearer ' .. token,
    ['content-type']  = 'application/json',
  },
  sink = ltn12.sink.table(tbl),
})

if res and code == 200 then
  resp = table.concat(tbl)
  resp = json.pdecode(resp)

  -- Found a value in table with setpoint here:
  FridgeSetp = resp["components"].cooler.thermostatCoolingSetpoint.coolingSetpoint.value
-- Found a value in table with temperature here:
  FridgeTemp = resp["components"].cooler.temperatureMeasurement.temperature.value
-- My goal - the Door contact sensor information was found here
  Door = resp["components"].main.contactSensor.contact.value
-- Found a value in table telling if rapid-coolmode is enabled here:
  RapidFreeze = resp["components"].main.refrigeration.rapidCooling.value
  
-- Updating With response
  grp.update('13/4/1',FridgeSetp)
  grp.update('13/4/2',FridgeTemp)
  grp.update('13/4/7',RapidFreeze)

-- Check if door already is open, if so check when it was opened.. and if over 8 seconds - Set alarmTag
  if grp.getvalue('13/4/6') == 'open' and Door == 'open' then
            if os.time() - grp.find('13/4/6').updatetime > 8 then
              -- set alarmTag
              grp.update('13/4/9', 1)
            else
              -- ReSet Alarmtag
              grp.update('13/4/9', 0)  
    end
    else  
  grp.update('13/4/6',Door)
         -- ReSet Alarmtag
        grp.update('13/4/9', 0)
  end  
--  log(resp)
else
  log(res, code)
end

Now the thing here is to search the table and log the response actively, Smartthings returs a huge Table with a lot of unndeeded data. For my fridge table above was OK, but I guess other SmartThings do look quite different.
Also did not check for Put commands, while I do not see any commands I want to give my fridge..

To find the Device Number to use in Script above, just run this once, and check the log.
This lists all your devices in Smartthings - cloud

Code:

https = require('ssl.https')
json = require('json')
ltn12 = require('ltn12')

token = 'Get your number from WEB-page'

tbl = {}
res, code = https.request({
  url = 'https://api.smartthings.com/v1/devices',
  method = 'GET',
  headers = {
    ['authorization'] = 'Bearer ' .. token,
    ['content-type']  = 'application/json',
  },
  sink = ltn12.sink.table(tbl),
})

if res and code == 200 then
  resp = table.concat(tbl)
  resp = json.pdecode(resp)

  -- This lists a Table with all your information:  
  log(resp)
else
  log(res, code)
end
